WebYou have 100 feet of 20 gauge wire and its resistance is 1.015 ohms at 20° C (room temp). If the temperature of the wire goes up 10°C, the resistance will change by 0.0399 ohms (10 degrees * 0.00393 per degree * 1.015 ohms = 0.0399 ohms). The wire resistance will now be 1.015 ohms + 0.0399 ohms = 1.0549 ohms. WebMar 8, 2024 · Table 9 in the National Electrical Code is provides copper and aluminum conductor resistance and ...
